Siemens SINAMICS S120 Function Manual page 313

Motor data sets can only be switched when a DDS is switched.
The motor data set switchover is used in the following cases, for example:
S Switching over different motors
S Switching over different windings in a motor (e.g. star-delta switchover)
S Adapting the motor data
If several motors are operated alternately on a Motor Module, a matching number
of drive data sets must be created. For further information about motor change-
over, see the "Motor switchover" section in the Function Manual.
One drive object can manage up to 16 motor data sets. The number of motor data
sets in p0130 must not exceed the number of drive data sets in p0180.
For 611U interface mode (p2038 = 1), the drive data sets are divided into groups of
eight (1– 8; 8– 16;...). Within a group, the assignment to the motor data set must
be the same:
p0186[0] = p0186[1] = ... = p0186[7]
p0186[8] = p0186[9] = ... = p0186[15]
p0186[16] = p0186[17] = ... = p0186[23]
p0186[24] = p0186[25] = ... = p0186[31]
If this is not the case, alarm A07514 is output.
If you need a precise representation of the data set structure of the 611U, 32 drive
data sets and 4 motor data sets must be configured.

Copying the command data set (vector only)
Set parameter p0809 as follows:
1. p0809[0] = number of the command data set to be copied (source)
2. p0809[1] = number of the command data to which the data is to be copied
(target)
3. p0809[2] = 1
Start copying.
Copying is finished when p0809[2] = 0.
